The image below shows the phase of mitosis where the chromosomes are lined up along the middle of the cell.
Which of the following best describes the phase of mitosis that will occur directly after the phase shown in the image?
A.
The next phase will be prophase, during which chromosomes condense, the nuclear membrane is dissolved, and centrioles produce spindle fibers.
B.
The next phase will be telophase, during which the chromosomes uncoil, new nuclear membranes are formed, and the spindle fibers dissolve.
C.
The next phase will be anaphase, during which sister chromatids separate and move away from one another towards the opposite poles of the cell.
D.
The next phase will be metaphase, during which the centromeres that join the sister chromatids connect to spindle fibers in
order to pull the chromosomes towards the opposite poles of the cell.
The correct answer is C. The phase shown in the image is metaphase, where the chromosomes are aligned at the equator of the cell. The next phase will be anaphase, where the centromeres holding the sister chromatids together split, allowing the chromatids to separate and move towards the opposite poles of the cell.

In order to determine the phase of mitosis that will occur directly after the phase shown in the image, we need to understand the different stages of mitosis and their sequence.
Mitosis is the process of cell division that ensures each new cell receives an identical set of chromosomes. The stages of mitosis are:
1. Prophase: Chromosomes condense, nuclear membrane dissolves, and centrioles produce spindle fibers.
2. Metaphase: Chromosomes line up along the middle (equatorial plane) of the cell.
3. Anaphase: Sister chromatids separate and move away from each other towards opposite poles of the cell.
4. Telophase: Chromosomes uncoil, new nuclear membranes are formed, and spindle fibers dissolve.
5. Cytokinesis: Division of the cytoplasm, resulting in the formation of two daughter cells.
From the options provided, the correct answer is C. The next phase after the phase shown in the image, where chromosomes are lined up along the middle (equatorial plane) of the cell, is anaphase. In anaphase, sister chromatids separate and move away from each other towards opposite poles of the cell.
Therefore, the correct answer is option C: "The next phase will be anaphase, during which sister chromatids separate and move away from one another towards the opposite poles of the cell."
